Blending in its simplest form is the combining of two or more materials
to produce a homogeneous mixture. These materials may be any combination
of particulate (solids blending) or particulate and liquid (liquid-solid
blending)
Normal tumble blending of free flowing materials provides a gentle
mixing action. For materials that tend to lump or for high intensity
blending, an internal agitator is utilized.
Critical to any blending operation is the quality of the blend,
i.e., batch variations. Different applications have varying requirements
for product uniformity.
Slant Cone
The asymmetrical geometry of the Gemco Slant Cone design offers
a very fast blend time. High particle mobility, plus the intermeshing
action of materials results in blend times up to 33 percent less
than other designs. In addition, this concept achieves more control
and more precise end product with blend variation as low as ½ percent.
V-Shape
Gemco V-shape blenders are very popular in a wide variety of industries.
They offer both short blending times…and efficient blending. The
blend is achieved by the constant, dividing and intermeshing particle
movement provided by two connected cylinders. This precise mixing
action results in blend variations of 1-2%. Each cylindrical leg
has an access cover for easy material loading and cleaning. The
V, as all tumble blenders, requires low maintenance and consumes
little horsepower.
Double Cone
The unique design of the Gemco D/3 Double Cone Blender results in
a high degree of particle mobility without the use of internal baffles.
This type of blender has a low profile, requiring less head-room
than a V-blender. One access cover means easier cleaning and inspection.
Invented by Gemco in 1935, the Double Cone is a proven performer
in a wide variety of industries, offering greater overall volume
and high efficiency with blend variations 1-2%.
Considerations In Blender Selection
Before selecting any blending system, it is necessary to understand
the characteristics of the materials to be blended, how the material
is transported to and from the blender, and how the blender will
be integrated into the plant. Key considerations include:
-
Material characteristics
- Loading
and unloading requirements
- Easy
product changeover
- Man-power
availability
- Material
lumping
- Single-floor
or multi-floor operation
- Daily
through-put requirements
- Process
flow* Specific industry regulations
- Dust
control
- Safety
Gemco
offers three different distinct vessel shapes, the Slant Cone, Double
Cone and V-shape. Three shapes provide the ability to select a system
best suited to your particular applications. All three designs can
be fitted with an internal agitator. |
